The relation between intra‐ and interpersonal factors and food consumption level among Iranian adolescent girls

Poor nutrition habits in adolescent girls endanger their health and are followed by serious systemic diseases in adulthood and negative effects on their reproductive health. To design health promotion programs, understanding of the intra‑ and interpersonal associated factors with treatment is essential, and this was the aim of this study.
This cross‑sectional study was conducted on 193 adolescent girls of age 11–15 years. Random cluster selection was used for sample selection. Food group consumption pattern was assessed by food frequency questionnaire. Also, perceived susceptibility/severity and nutritional attitude as intrapersonal factors and social support as interpersonal factor were assessed. The relationship between food group consumption level and nutritional attitude and perceived treat (susceptibility/severity) as intrapersonal factors and perceived social support as interpersonal factor were assessed by linear multiple regression and analysis of variance (ANOVA).
Results showed that the level of sweetmeat food consumption was related to perceived social support (P = 0.03) and nutritional attitude (P = 0.01) negatively. In addition, an inverse and significant association was found between the level of junk food intake and informational perceived social support (P = 0.004). The association between the level of fast food intake and the perceived parental social support for preparation of healthy food was negatively significant (P = 0.03). Breakfast consumption was related to nutritional attitude (P = 0.03), social support (P = 0.03), and perceived severity (P = 0.045).
Results revealed that perceived social support and nutritional attitude are the important and related factors in dietary intake among girls, and promotion of social support and modification of nutritional attitude may lead to healthy nutritional behaviors among them.
